The majority of the
current evidence examining an integrated model of pharmacist and GP care is
positive. A recent systematic review and meta-analysis of pharmacist-delivered
services in general practice included 38 studies. Of these, 25 reported
positive effects on at least one primary outcome measure and 13 demonstrated no
effect.10 Interventions usually involved medication review, with or without
other activities delivered with the GP such as education, medication monitoring
and adjusting therapy. Four clinical markers were used to assess the effect of
interventions – blood pressure, glycosylated haemoglobin, cholesterol, and the
Framingham Risk Score. Results of the meta-analysis favoured the pharmacist
intervention with significant improvements observed in all clinical markers
compared to the control groups. Positive effects were more likely to be seen
with pharmacist-delivered multifaceted interventions in conjunction with
follow-up of patients compared to interventions that delivered a service in
isolation. There was limited or no effect on outcomes related to quality of
life, patient satisfaction, symptoms, and use of health service.
Individual studies have
shown improvements in other outcomes including:
- identification and
reduction of medicine-related problems
- patient adherence to
medicines
- process measures such as
timeliness
- appropriateness of
prescribing
- reduction in total
number of medications.11-16
The transition of
patients with chronic and complex diseases from hospital to the community is a
critical time with an increased risk of medication misadventure and
re-hospitalisation.17 A UK study found that sending discharge letters to
practice pharmacists as well as GPs improved the coordination of care and
implementation of consultant recommendations for treatment.18
The large-scale PINCER
trial found that a practice pharmacist-led intervention to reduce clinically
important medicine-related problems was cost-effective.19 Australian studies
have also reported cost savings ranging from $44–$100 per patient.20,21 A 2015
report commissioned by the Australian Medical Association and published by
Deloitte Access Economics indicated that for every $1 invested, $1.56 in
benefits could be generated. This equates to $544.87 million in savings over
four years.22
One of the key elements
described in the literature is that, in addition to becoming integrated into
the general practice team, the pharmacist’s access extended to the patient’s
electronic health record.11-16,18-21 This allows the practice pharmacist to
view the patient’s past medical history, pathology, specialist correspondence
and previous medicines, which are all crucial when providing pharmaceutical
care. It also facilitates better care coordination and collaboration between
the practice pharmacist, GP and other members of the integrated team.
